Distributor gear oiling

Distributor gear oiling
I just read this on this website https://oldsjunction.classicoldsmobi...sfaq/ofign.htm.
" The oil rail (in an Olds) for the drivers side valve lifters ends just before the distributor. It should have a pipe plug with a .040" hole to spray oil on the distributor gear. If someone put in a plug with no hole, the gears and lower distributor bearing will have a short life. "
Can anyone confirm this ? I just built a 69 350 and used new oil plugs and they DID NOT have any lube hole.

You can drill the hole yourself easily enough. I drill a 1/16" hole most of the way through the plug then finish with a 0.040" bit. Very easy on a brass plug.
Or post a parts wanted. Several guys here have piles of the various plugs.

I have driven the car about 100 miles. I have had the distributor out about 10 times for various reasons and the gear is oily every time.
I may have used the original plugs and got lucky and put it in the right location, I hope.
Does the oily gear indicate that I may the orifice plug in there after all. What visual symptoms would there be if the orifice is not there ?

I made a small mirror and could not see hole in rear plug. Also no stream of oil when priming engine.
I made a few phone calls.
Tony Ross Racing says he has run without .040 orifice and says there is plenty of splash from rear crank counterweight, also timing chain is not a problem although the front plugs are unique and I reused them.
According to Mondello the factory did not have these oiling holes.
When I disasembled the engine it had only minor cam gear and distributor gear wear in over 100,00 miles of use.
Every time I pull the distributor after running, the distributor is dripping oil.
I will probably never put more than 5000 miles on the car in the next 10-15 years.
I'm 70 so the engine will probably outlast me.
